Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Mean diameters (distribution type: volume): D (v, 0.1) = 1.10 μm; D (v, 0.5) = 2.12 μm; D (v, 0.9) = 4.11 μm
Additional information
A study was performed in accordance with ISO 13320 using laser diffraction in water as dispersion liquid. The test substance was introduced in the dispersion unit filled with water under constant stirring. The obscuration (fraction of incident light that is attenuated due to extinction by particles) did not exceed 25 % and did not fall below 10 %. The test item was treated with ultrasonic and the measurement was started. The analysis was finished when the whole amount of the test substance had passed the laser beam.
The mean diameters applying Fraunhofer approximation were: D (v, 0.1)= 1.10 µm; D (v, 0.5)= 2.12 µm; D (v, 0.9)= 4.11 µm
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
